FREEZER.

LEPECIIE'ICJATION forming part of Letters Patent No. 391,125, dated October 16, 1888.

Application filed June 6, 188B. Serial No. 276.172.

(No model.) Patented inFrance June Q3, 1881, No. 143,560.

To all whom it may concern:

Be it known that I, THEoDoRE LEON DELPY, of Paris, France, have invented a new and Improved Freezer, (for which I obtained Letters Fatent No. 143,560, granted to me in France June 23, 1881,) of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved freezer which is simple and durable in construction and very effective in operation, being specially adapted for cooling liquids, bottles, meat, and other articles and substances.

The invention consists of certain parts and details and combinations of the saine, as will be fully described hereinafter, and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of the improvement. Fig. 2 is a sectional plan View of the same on the line .c a of Fig. l. Fig. 3 is a sectional plan view of a freezer to be used in connection with the improvement. Fig. 4 is a sectional plan view of the same on the line y y of Fig. 4; and Fig. 5 is a side elevation, partly in section, of one of the shafts.

The improved freezer A is provided with a receptacle, B, preferably made with double walls and mounted on legs C for supporting the freezer on the floor. On top of the receptacle B is held a cover, B', of sufficient height to support the machinery for operating the several devices hereinafter more fully described. A pipe, D, passes through the wall of the receptacle B into the interior of the latter and is formed into a coil, D', extending around the inner wall of the receptacle B and then passing out again at the opposite side, as is plainly shown in Fig. 1. A liquid or gas to be cooled can be forced through this pipe, being cooled while passing through the coil D', held in contact with the freezing-mixture in the receptacle B.

In the bottom of the receptacle B, and in the center, is held a plate, E, on which rests a vessel, F, preferably made star-shaped, as shown in Fig. 2, being provided at its upperend with au annular iiange, F', from which extends a vertical annular flange, F2, on which [its the cover G for closing the open end ofthe receptacle F. To the bottom of the receptacle B are secured the upwardly-extending bars H, resting against the sides of the vessel F, as plainly shown in Fig. 2, so as to prevent the said vessel from turning on the plate E.

In the middle of the cover B is mounted to turn the vertical shaft I, extending into the interior of the said cover and carrying near its inner end a bevel gear-Wheel, J, meshing into a bevel gear-wheel, K, secured to the horizontal shaft K, mounted to rotate in suitable bearings in the said cover B. On the outer end of the shaft K is secured a crankarm, L, for turning said shaft K', so as to impart a rotary motion by means of the bevel gear-wheels K and J to the shaft I. On the lower end of the latter are secured the arms N, extending radially and then bent downward, being formed at their lower ends into beaters O, extending into the receptacle B, their lower ends reaching to within a short distance ofthe bottom of the receptacle B. In the bottom of the latter is secured a faucet, P, for draining the receptacle whenever desired.

The operation is as follows: Vhen the machine is in the position shown in Figs. l and 2 and the receptacle B contains the freezingliquid, and the vessel Fis held inthe saidliquid and contains the liquid to be frozen, then the operator turns the crank-arm L, so as to rotate the shaft I, whereby the arms N carry the beaters O around in the freezing-mixture, so that the latter is agitated and is brought in contact with the surface of the vessel F. rlhe liquid contained in the vessel F is thus cooled rapidly. After the cooling process is finished, the operator lifts the cover B from the receptacle B, whereby the driving mechanism and the beaters O are lifted out of the receptacle B. The vessel F can then be conveniently lifted off of the plate E out of the receptacle B and emptied of its cooled contents. y

Instead of having a liquid in the vessel F, I may place bottles or other substances in the same to be cooled in the same manner as above described. Then the beaters O agitate the freezing-mixture in the receptacle B, the said mixture comes constantly in contact with the coil of pipe D', so that any gas or liquid pass- IOO ing through the said coil of pipe D is rapidly cooled.

In order to make ice-cream or other similar substances, I employ a vessel, Q, (shownv in Figs. 3 and 4,) instead of the vessel F, as above described. This vessel Q is set on the plate E and is provided with a cover, Q', through which passes a shaft, R, having its bearings in the bottom of the vessel Q and in the said cover Q. On the upper end of the shaft R is formed a screw-thread, R', adapted to screw into the screw-threaded block I,seeured on the lower end of the shaft I, as shown in Figs. 1 and 5. On the shaft R, inside of the vessel Q, are formed wings or plates S, having perforations.

The mixture to be frozen is placed in the vessel Q, which is set on the plate E and connected by its shaft R with the shaft I, as above described. When the operator now turns the crank-arm L, the shaft I operates the beaters O, and at the same time revolves the shaft R, so that the mixture in the vessel Q is agitated until it is frozen. It is understood that the freezing-mixture in the receptacle B exerts its freezing; properties against the exterior of the vessel Q in the manner as above described in reference to the vessel F. It is understood that by agitating the freezing-mixture and at the same time agitating the mixture to be frozen inthe vessel Q the process of freezing the latter takes place very rapidly.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- Y The combination, with the receptacle B, provided with the cover B, of the horizontal shaft K', provided with the bevel gear-wheel K and crank-handle L, the vertical shaft I, provided with the gear-wheel J, the beater N O, and the screw-threaded block I below the beaters, and a closed vessel in the receptacle, substantially as described, whereby provision is made for utilizing one or two sets of beaters, as may be found convenient, as set forth.
